Installshield and Wise installation products will not install software on hard drives systems greater than a terabyte

I have tried to install several products to a large disk array system on the D: drive that has a 1.5 TB capacity and 1.1TB free space. In the custom setup dialog, I change the install location from c:\program files\product to d:\product and when I click the Next > button, the out of disk space dialog appears saying hat there isn't enough free space on the drive.

It lists the correct numbers for the c: drive (not a large drive, 120 gigabyte in size), but the D: drive (which is 1.5TB in size, with 1.1TB free space), shows as having -419GB capacity and -963GB free and Required at 326MB.

I have seen this problem with dozens of products using InstallShield and Wise as the installation app (that's most of the apps for windows!). I have searched installshield.com, installsite.org, and support.microsoft.com, www.wise.com - just to name a few.

Any ideas how to get around this problem? (besides reducing my disk array to smaller than a terabyte)

Who is Participating?

Scratch that workaround, I see it's the disk size rather than the free space that's negative, you'll have to shrink the volume with a partition manager, install it and then resize it again, all of which is risky so back it up first.

I know it makes for headaches, but CHECK DISK SPACE is (I think) only required if you also use the command INSTALL. To get around your problem, try COPY instead of INSTALL. I know you'll end up with a larger EXE, but for small programs it might work.

If I understand what you are saying, is to "change an option in the InstallShield or Wise product". I do not have access to those settings within InstallShield or Wise. Think of me as an "end-user", who is installing packages I purchased from dozens of other vendors, who might use Wise or InstallShield to install their application on my servers. Those installation products do not calculate large disk arrays correctly, when they are over a terabyte in size.

I am looking for a way to "fool" or "trick" InstallShield or Wise into installing the required application onto the large disk array.

Interesting, you must be one of the first people to ever try to install software on a volume greater than a terabyte. Obviously they have used a value for the disk size but made the mistake of treating it as a normal number rather than a positive. I doubt they would bother to fix the problem if you reported it since nobody installs programs on disks that big.

We decided to add another hard disk array as the bootable C drive (keeping it small: < 250gig)- and reinstalled all the software. :-(

This is going to be a MAJOR issue soon with most software vendors using InstallShield and Wise, as we will see more and more companies using larger disk arrays (gt terabyte systems) in the near future.

I don't see that happening. Terabyte sized disks are for data, who would normally install a program on a data disk?

You have a 250GB C: drive? I don't want to appear rude but that's crazy, nobody has a boot partition that size. Windows OS is a bit greedy but 12GB would be considered big for C:, if there were many many progs that were run on it another 20GB for executables may be justified but that's a hell of a lot of code to run unless you have more than 8 CPUs. I think you need to see what data you have currently on C: and move it to another drive.

We never were able to get this resolved. So, we installed another mirror to get around the issue for now.
